Shleiger \paper Forces for the particles with a zero energy in Kerr metric \paperinfo The particles with negative energy might exist in the ergosphere of a rotating black hole due to collision or decay. We also know that there might be particles with zero energy in this region. In this paper we find out how the geodesic equations depend upon the energy and consider forces which act on the particles with zero energy. Also, we investigate the question how these forces for particles with zero energy differ from the ones in the case of usual positive energy E. We find out that the forces in the usual case are less than in the case of zero energy. \jour Physics of Complex Systems \yr 2021 \vol 2 \pages 4
